Linux Lennart Poettering, the author of systemd, has announced: "I just put a first version of a wiki document together that lists a couple of easy optimizations to get your boot times down to [less than] 2s. It also includes a list of suggested things to hack on to get even quicker boot-ups."

Boot times matter because there are many brain dead journo's out there that think that boot times are a measure of how fast a particular distro is.

As opposed to some real life benchmarks but that would take real work on their part rather than hitting 'Next' in the installers and using that for their copy.

Alot of people here think boot time doesn't matter. I know hibernation makes boot times less frequent and less relevant to some people. However sleep/hibernation modes represent a great deal of complexity between OS/BIOS/hardware, and is frequently the cause of driver bugs. If turning on a computer was as fast as waking it up from sleep, then it might eventually enable a OS to do away with the ugly complexities of hibernation.

In my opinion one should be able to turn on and use a computer much like they turn on and use a TV - only waiting for the display to "warm up".

Hibernation has other benefits like being able to keep all your programs/documents opened. Even if you have a session manager that saves state on shutdown, it still needs to reopen everything one by one as opposed to loading an image into ram.

Does sleep/hibernation support in drivers really add complexity, or just require drivers to be written correctly?

Also, saving the state of the 30+ terminal and app windows I have open is not simple for my desktop -- no desktop I've ever used has done it correctly.

Hibernation rarely works in Linux world.
It's always something, either your Wifi, soundcard or whatever you have connected to USB, but one single faulty driver makes the whole hibernation as bootup concept useless.
